My right ear did not clear and I lost the hearing in my ear. I proceeded to treat myself for a few days with no success. Sought medical care and the doctor said I had a very slight irritation in my ear but the ear canal was closed to 1/3 its normal size. He told me to discontinue using the bluetooth; treated, and I now have about 75% of hearing back but still have a constant white noise in my ear. Can’t say this was actually caused by the bluetooth but don’t want to take any more chances.
